October seventeenth in the morning，Lu'an City, Anhui ProvinceSThe construction site of the reconstruction project of the connecting section of the 245 Huoqiu Chengguan-Hehuofu Expressway is crowded with people.，It's very lively，Trinity“Technology blue”Unmanned compactor group is once again intelligent、Unmanned construction becomes the focus of the whole audience，Hundreds of experts at the scene、Customer、The media participated in the unmanned construction observation meeting.。

“Unmanned pressure officially begins.！”Accompanied by an order，By 2SPR300C-8 Rubber-tired roller、3 setsSTR130C-8 double drum rollers and 2SSP90C-The unmanned paver group composed of 8 pavers was dispatched in an orderly manner.，Start fully automated joint paving and rolling operation。

Application of Sany Unmanned Pressing Machine GroupBeidou positioning system、High speed communication system、Obstacle avoidance perception system and other intelligent technologies，According to the preset paving speed、Running track、Cooperative operation of rolling speed and number of times，The system adjusts the construction parameters in real time according to the site conditions.，Ensure high quality paving and rolling。 

Introduction of the person in charge of site construction，The unmanned compactor group can control the construction track accuracy within 3 cm.，Independently developed by SanyHigh-precision road edge recognition technology，Roller-realizable"Zero welt"Rolling，The uniformity of paving and rolling and the compactness of the pavement are ensured.、Flatness at the same time，But also can effectively solve the common quality problem of insufficient edge rolling in conventional construction.。 

This unmanned construction observation activity is sponsored by Liju Group.，Huoqiu County Traffic Bureau and Guizhou BridgeSCo-organized by Project Department 245，Jointly organized by Lu'an Jumao and Sanyi Jizhi Road Science and Technology，It has received the attention of many media.。In the field of road engineering construction,，Technicalization、Digitize、Intelligent，Internet of Things and Big Data Fusion is a New Era、Driven by the trend of new infrastructure，The new technology of unmanned intelligent paving and rolling is the industry's leading technology.。At present，The new platform of digital control system jointly developed by Liju Group and Sanyi Road Machinery has reached the leading position in China.、International first-class level。 

Sany and Liju Group have already reached strategic cooperation in 2021.，At the beginning of this year, it reached a strategic cooperation of purchasing orders of 100 million yuan.，Involving more than one type of construction machinery and equipment，This joint construction of unmanned spreading machine group is the first cooperation between Sany and Liju Group in the application and construction of unmanned spreading technology.，It also marks that the two sides will develop a deeper level in the field of intellectualization.、All-round cooperation，Hand in hand“Intelligent construction”A new era！
